Early percutaneous external drainage procedure in treatment of pancreatic pseudocyst / 한국간담췌외과학회지

ABSTRACT

BACKGROUND: Pancreatic pseudocyst is the most common cystic lesion of pancreas, which is formed with leakage of pancreatic juice by pancreatic duct injury, surrounded by around intraperitoneal organs and tissue. METHODS: The study subjects consist of 18 patients who undergone primarily percutaneous catheter drainage(PCD) from January of 1995 to December of 1998 at Pusan National University Hospital. RESULTS: The peak incidence was in the age group of 20 to 40 years and male gender was somewhat dominant. The cause of pancreatic pseudocyst was mainly trauma(61.1%), the most common location of injury site was body of pancreas. The initial diameter of pancreatic pseudocyst was above 6 cm(72.2%) and the size was reduced in 13 cases(72.2%) of 18 cases during treatment. Mostly the amount of drainage through PCD was below 100mL(55.6%) and the amount was decreased in 13 cases during treatment. Spontaneous resolution of pancreatic pseudocyst was occurred in 11 cases, among them 3 cases were recurred. Persistent or recurred cases were undergone secondary procedure, internal drainage in 6 cases, retrial of PCD in 2 cases, distal pancreatectomy in 1 case, zther in 1 case. CONCLUSION: The percutaneous catheter drainage performed within initial 6 weeks for spontaneous resolution of pancreatic pseudocyst or maturation of cystic wall is considered as alternative treatment of pancreatic pseudocyst.
